[ Upstream commit 4d62e81b

 ]

Giancarlo Ferrari reports the following oops while trying to use kexec:

 Unable to handle kernel paging request at virtual address 80112f38
 pgd = fd7ef03e
 [80112f38] *pgd=0001141e(bad)
 Internal error: Oops: 80d [#1] PREEMPT SMP ARM
 ...

This is caused by machine_kexec() trying to set the kernel text to be
read/write, so it can poke values into the relocation code before
copying it - and an interrupt occuring which changes the page tables.
The subsequent writes then hit read-only sections that trigger a
data abort resulting in the above oops.

Fix this by copying the relocation code, and then writing the variables
into the destination, thereby avoiding the need to make the kernel text
read/write.

This reverts commit c17e9377

.

The lpc32xx clock driver is not able to actually change the PLL rate as
this would require reparenting ARM_CLK, DDRAM_CLK, PERIPH_CLK to SYSCLK,
then stop the PLL, update the register, restart the PLL and wait for the
PLL to lock and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK
PLL.

Currently, the HCLK driver simply updates the registers but this has no
real effect and all the clock rate calculation end up being wrong. This is
especially annoying for the peripheral (e.g. UARTs, I2C, SPI).

[ Upstream commit 06862d78 ]

We get suspcious RCU usage splats with cpuidle in several places in
omap_enter_idle_coupled() with the kernel debug options enabled:

RCU used illegally from extended quiescent state!
...
(_raw_spin_lock_irqsave)
(omap_enter_idle_coupled+0x17c/0x2d8)
(omap_enter_idle_coupled)
(cpuidle_enter_state)
(cpuidle_enter_state_coupled)
(cpuidle_enter)

Let's use RCU_NONIDLE to suppress these splats. Things got changed around
with commit 1098582a ("sched,idle,rcu: Push rcu_idle deeper into the
idle path") that started triggering these warnings.

For the tick_broadcast related calls, ideally we'd just switch over to
using CPUIDLE_FLAG_TIMER_STOP for omap_enter_idle_coupled() to have the
generic cpuidle code handle the tick_broadcast related calls for us and
then just drop the tick_broadcast calls here.

But we're currently missing the call in the common cpuidle code for
tick_broadcast_enable() that CPU1 hotplug needs as described in earlier
commit 50d6b3cf

 ("ARM: OMAP2+: fix lack of timer interrupts on CPU1
after hotplug").

commit c4295ab0 upstream.

After Commit 3499ba81 ("xen: Fix event channel callback via
INTX/GSI"), xenbus_probe() will be called too early on Arm. This will
recent to a guest hang during boot.

If the hang wasn't there, we would have ended up to call
xenbus_probe() twice (the second time is in xenbus_probe_initcall()).

We don't need to initialize xenbus_probe() early for Arm guest.
Therefore, the call in xen_guest_init() is now removed.

After this change, there is no more external caller for xenbus_probe().
So the function is turned to a static one. Interestingly there were two
prototypes for it.

The panel data sheet defines the chip-select to be active low.

Now, with the arrival of

commit 766c6b63 ("spi: fix client driver breakages when using GPIO descriptors")

the logic of interaction between spi-cs-high and the gpio descriptor flags
has been changed a second time, making the display broken again. So we have
to remove the original fix which in retrospect was a workaround of a bug in
the spi subsystem and not a feature of the panel or bug in the device tree.

With this fix the device tree is back in sync with the data sheet and
spi subsystem code.

[ Upstream commit 2cc0bfc9 ]

The PHY address bit 2 is configured by the LED pin. Attaching a LED
to this pin is not sufficient to guarantee this configuration pin is
correctly read. This leads to some platforms having their PHY at
address 0 and others at address 4.

If there is no phy-handle specified, the FEC driver will scan the PHY
bus for a PHY and use that. Consequently, adding the DT configuration
of the PHY and the phy properties to the FEC driver broke some boards.

Fix this by removing the phy-handle property, and listing two PHY
entries for both possible PHY addresses, so that the DT configuration
for the PHY can be found by the PHY driver.

commit 8a996b2d upstream.

The Ux500 platforms have some memory carveouts set aside for
communicating with the modem and for the initial secure software
(ISSW). These areas are protected by the memory controller
and will result in an external abort if accessed like common
read/write memory.

On the legacy boot loaders, these were set aside by using
cmdline arguments such as this:

  mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M
  mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M
  hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M
  mem=638M@385M

Reserve the relevant areas in the device tree instead. The
"mali", "hwmem", "mem_ram_console" and the trailing 1MB at the
end of the memory reservations in the list are not relevant for
the upstream kernel as these are nowadays replaced with
upstream technologies such as CMA. The modem and ISSW
reservations are necessary.

This was manifested in a bug that surfaced in response to
commit 7fef431b

 ("mm/page_alloc: place pages to tail in __free_pages_core()")
which changes the behaviour of memory allocations
in such a way that the platform will sooner run into these
dangerous areas, with "Unhandled fault: imprecise external
abort (0xc06) at 0xb6fd83dc" or similar: the real reason
turns out to be that the PTE is pointing right into one of
the reserved memory areas. We were just lucky until now.

We need to augment the DB8500 and DB8520 SoCs similarly
and also create a new include for the DB9500 used in the
Snowball since this does not have a modem and thus does
not need the modem memory reservation, albeit it needs
the ISSW reservation.
